izzemfw W Mia-12 main operating device which will'be hereinafter more fully described.

In addition to the primary and secondary change s eed devices there is provided a reversing evice which preferablyperforms its function in connection with the "secondary bined width of the gears 9 and 13 and is normally held in such position that it can be thrown into mesh engagement with, both of the gears 9 and 13 when the latter are in the position shown in Fig. 1. On the outer end of shaft 21, there is mounted an arm 33 which projects into the path of extensions nr studs Y 34 and 35 mounted upon a shaft 20 forming a part-of the main operatin device which will now be described in detai The bell crank 17 forming a part of the primary clutch actuating device is connected with a speed change operating shaft 20 by having its end interposed between two annu lar shoulders 36, and the link 31 of the secondary speed actuating device is connected lowing parts.

with an arm 37 mounted on shaft 20. Said shaft 20 may be mounted in any suitable form of bearings aliording' said shaft a free oscillatory and longitudinal movement. The means for effecting such oscillatory longitudinal movement of the shaft 20 consists of the fol- 38 designates a controller shaft mounted at one on in. a suitable bearing 39 and pro- .yided with a shifting member 40 non-rotal. to

mounted on shaft 20 and tively and non-slidably mounted thereon. Said shifting member comprises a hub portion 41 and a bifurcated extension 42 con-' nec'ted with a part 43 of an oscillatory de-v vicex' Said oscillatory device consists as shown of the part or collar 43 which" is rovided with an arm 44 connected by a lin 19 with an arm 45 whose hub 46 is mounted on shaft 38. A controlling member in the form of a lever referably rigidly secured by being forme integral with the hub 46 which latter is slidably and non-rotatively mounted on the shaft 38. A segment guide 47 for the controlling lever 18 is mounted upon any suitable stationary part such for instance as 48 and is provided with a lurality of slots in its up er face 49 for limiting movement of the ever 18. At extreme lateral points slots 50 and 51 are provided each of which permit an extreme longitudinal swing of the lever 18. In order to aiford lateral movement of the lever the slots 50 and 51 t senses are connected by a transverse opening 52. The rear portion of the upper face along said transverse opening presents a continuous margin 53 while the forward portion 54 is provided with a slot 55.

The operation is as follows: The parts in Figs. 1 and 2 occupy adjusted positions wherein the intermediate clutch 8 is out of coupling relation with clutch portions 5 and 5 in which position the wheels 5 and 6 run freelyon the-sleeve 7 and. permit operation of the driving shaft 1 without operating the axle 2. Assuming that the operator desires a relatively high speed from the primary change speed device and a direct drive with the gear 15 he will first move the lever 18 laterally in to the slot 50 which movement will through arm 45 link 19 and arm 44 rotate the shaft 20 in the direction of arrow 55 thereby acting through arm 37 link 31 and lever 27 to throw the clutch members 10 and 11 into coupling relation effecting direct drive connection between sleeve 7 and the car 15. The operator will next swing the ever 18 in the direction of the arrow 57 thereby turning shaft 38 in the direction of arrow 58 and shifting shaft 20 in the direction of the arrow 59 and servin r through the connections hlereinbefore descri ied to throw the member 8 into coupling relation with the clutch 6 This adjustment gives a direct drive from gearsA, 6 and clutch members 10 and 11. Assuming now that the operator desires to change speed to a relatively slov or rate he will swing the lever 18 in the s ot 50 in the direction of the arrow 60 which will serve to shift the shaft 20 in the direction of the arrow 61 without oscillatim the same and will sort e to disengage the clutch mem her 8 from; member 6 and throw it into engagement ivith member 5* thereby adjusting the parts to drive through gears 3 and 5 direct through clutch 10 and 11. Assuming now that the operator wishes to drive through the secondary change speed device he will move the lever 18 into slot 51 which will cause a rotation or oscillation of the shaft 20 in the direction of arrow 62 and will serve to throw the clutch 10 out of engagement with the clutch 11 and throw wheel 9 into mesh with wheel 13 thereby driving from sleeve 7 through gears 9, 13, 14 and 12-; It will be understood that when the lever 18 is in an intermediate position the clutch member 8 will also be in an intermediate position therefore the lateral movement of the lever 18 from slot 50 to slot 51 mere y serves to change the relation or posi tion f gear 9 and clutch 10, the speed being changed only by a longitudinal swing of the lever 18. In the first adjustments described relatively high and low speeds were set through direct connection with the gear 15 but in the adjustments now about to be de scribed the two relatively high and low speeds direction of rotation when in mesh with slots-50 and 51being so proportioned as to oer,

will each be reduced by the secondary aha-n ge speed device as will be obvious from the proportions of the gearing thereof. With the inion 9 in mesh With the pinion 18 end the 2 ever 18 in slot 51 the operator can adjust the clutch memberS into eonplin relation with either of the members 5 or 6 by swing ing the lever 18 in the slot 51 in the manner hereinbe t'ore described.

Assuming that the operator desires to reverse the vehicle and drive the same bacl wardly he will first move the lever 18 into an intermediate position in the passageway 52 so that the lever 18 is in register with the slot l 55. In this adjustment the pinion Q will be in the position shown in Fig. 1 and the memher 8 will be put of coupling relation with l clutches 5 andlj It Will be noted that the pinions "9 and l3 are now out of operative relation so that theycan rotate in. opposite directions. By throwing the lever 18 in the direction of arrow 57 into the slot the shaft 20 will be shifted in the-direction ol arrow 59 and the member 8 willhe tl'irown into coupling relation with the member as. It will be noted that slot is somewhat longer than slots 50 and 51 therefore "vi-"hen the lever 18 is swung to the limit of its movement the stud 34 will engage arm and swingthe pinion 16 upwardly into mesh with pinions 9 and 13 thereby reversing direction of rotation of pinion 13 from pinion 9 and thereby serving to reverse the direction of rotation of the axle l l hen the lever 18 is swung rearwardly out of slot 55 into passa e way 52 the weight of pinion 16 will be en cient to automatically throw .it out of mesh with pinions 9 and 13 by gravity.

. By reference to Fig. 3 it will be noted that ample play isgprovided between studs 34 and 35 to permit'la sufficient shift of the shaft 20 to effect ordinary change speed adjustments without throwing in the reversing gear, the

prevent snificient movement of the lever 18 to throw the ear 16 into a mesh position. However the s 01; 55 permits suflieient et 'tra movement to effect engagement of the stud 3i and arm 33 to throw in the reversing gear. if for any reason the 'gear 16 should fail to drop out of a mesh engagement the stud will engage the arm 33 when. the lever 18 assumes the position shown in Fig. 2 to positively throw said gear 16 out of mesh relation with the gears 9 and 10.
